This is my 2nd summer with a pool. Last summer we drained the water out and started over because the previous home owner didn't maintain it very well. This year however we just added more water and now I can't get it clean. I've done liquid shock, adjusted the Ph levels, added algaecide...it was still cloudy. So then I blindly vacuumed the bottom, hoping it would help...did that, waited a day, still cloudy. Finally today I went to granule shock, put that in...still cloudy. I'm about to lose my mind!! Any help or ideas?
